I used tac22 in my T1x for practice on a usbr target for our match this weekend. Off a bipod and a glove rolled up in a weightlifting sleeve for a rear bag I shot 219, 206, 211. Pretty solid for $3.53 a box at Rural King.
I took my Savage MK2 FVT out again today with a buddy and tried TAC22 again. Opened a new box and it shot half way decent:
Of course it's not match grade ammo, but it shot better today than it did the other day. Here's how the rifle did today with a little better ammo, but that ammo is about twice the cost:
However, when Automatch shoots better in most of my rifles, it kind of defeats the purpose:
That's just been my limited experience with TAC22. I know a lot of you guys have had better luck with it.
